| abstract |
The present invention generally provides a method for controlling polymer properties. In particular, the present invention relates to copolymer density and / or melt by changing at least one or more of the following parameters: molar ratio of hydrogen to ethylene, molar ratio of comonomer to ethylene, partial pressure of ethylene, and reactor temperature. A method is provided for controlling the comonomer composition distribution of a polyolefin, such as an ethylene-α-olefin copolymer, without substantially changing the index. |
